Can I Use a Charger that Provides the Same Voltage But a Different Amperage?

Can I use a charger that provides the same voltage but a different amperage?

Yes.With a couple of caveats, of course.Getting the right power supply, involves matching voltage, amperage, and polarity. And each have different constraints.

 If you replace the power supply for some reason with one that has a maximum amperage rating that is less than the previous and less than what your device actually requires, then you may end up with a burnt out or (at least) overheating power supply, and the device itself may not function, or may not do so well.

In short, when replacing an external power supply or charger:

1.Make sure that the voltage matches as closely as possible.

2.Make sure that the new supply is rated to provide the same amperage or more.

3.Make sure that the connectors match, both in physical form and in polarity.

Wireless Charging Technology is Future Trends

Charging without wires is not the only reason to embrace wireless charging. If your phone is water- or dust-resistant, the necessary charging port covers can be fiddly and annoying; with wireless, you don’t have to touch them at all.

There are other benefits. The most common wireless charging standard, Qi, is available in all kinds of public places, especially in the US - so if you’re in an airport or hotel you can often find a wireless charging pad.

There’s another benefit. Because wireless charging is a universal standard, you could potentially use one set of chargers for a whole bunch of devices - phone, smartwatch, tablet and so on.

That could reduce the amount of cables and international power adapters we make and discard. In the very long term, we might even have wireless charging pads for electric cars.
